Natural scale graphite is a non -metal mineral with unique physical chemical properties such as high temperature resistance, antioxidant, corrosion resistance, heat shock, high strength, good toughness, high self -lubricating strength, high heating and conductivity. Graphite series products are mainly used for metallurgy, machinery, electronics, battery, chemical, light industry, military, defense, aerospace, fire -resistant materials and other industries. It is an important non -metal raw material for high -tech today.
Graphite's conductivity is 100 times higher than that of ordinary non -metal minerals, and it is widely used in industry and life conductive and anti -static materials. What are the main applications of scales graphite?
1. For plastic or rubber, different conductive rubber and plastic products can be made. This product has been widely used for anti -static additives, computer anti -electromagnetic screens, etc. In addition, there are also extensive application prospects in the fields of micro TV screens, manipples, solar batteries, and light -emitting diodes.
2. For resin and coatings, it can be compounded with the conductive polymer to make a composite material with excellent conductive performance. The conductive graphite coatings play an irreplaceable role in home anti -electrostatic and hospital building anti -electromagnetic radiation with its excellent conductivity, economic affordable price and simple operation.
3. The use of electrical graphite powder in ink can make the surface of the printed matter have the effects of conductive and anticrocating.
4. When used for conductive fiber and conductive cloth, the product can shield electromagnetic waves. Many of the radiation protection clothes we usually see are using this principle.
As a key material for lithium ion batteries, graphite negative materials have gradually become the mainstream of the negative electrode material market, accounting for about 70%of the market share. Since the development of lithium ion batteries, a variety of positive material systems have been derived, such as lithium cobaltate, lithium iron phosphate, nickel manganate cobalt lithium, and nickel cobalt lithium. But the graphite negative material system has been used until now.
Graphite anode materials are usually divided into natural graphite and artificial graphite. Natural graphite comes from the mines, which are made from Heilongjiang, Qingdao and other places. The artificial graphite is derived from coal and petrochemical by -products. It consists of a by -products of oil or coal chemical asphalt or decompression residue oil. It is delayed to coke into a needle -shaped coke, and then made of granules and graphization.
